On the graph of the equation 8x – 3y = 24, what is the value of the y-intercept?

ella [17]

8x - 3y = 24

y-intercept ⇒ x = 0

subtitute

8 · 0 - 3y = 24

-3y = 24 |divide both sides by (-3)

y = -8

The midpoint of AB is M(1, 1). If the coordinates of A are (3, -3), what are the coordinates of b

Black_prince [1.1K]

Answer:

Midpoint is ( Average of x’s, Average of y’s )

1 = (x + 7)/2

2 = x + 7, x = - 5

and - 1 = (y + (-4))/2

so - 2 = y - 4 and y = 2

Pt B = (- 5, 2)

A factory produces some batteries daily. 7/8 of the batteries are packaged immediately. 2/3 of the

frozen [14]

Answer:

$\frac{1}{24}$

Step-by-step explanation:

Let the total number of batteries produced daily be represented by x.

7/8 of the batteries are packaged immediately.

So the total number of packaged batteries = $\frac{7x}{8}$

Remaining batteries = $x-\frac{7x}{8}$

= $\frac{x}{8}$

Two third of the remaining batteries are sent to charity.

So the total number of batteries sent to charity= $\frac{2}{3} * \frac{x}{8}$

= $\frac{x}{12}$

Remaining batteries are faulty.

So the total number of faulty batteries = $\frac{x}{8} - \frac{x}{12}$

= $\frac{3x - 2x}{24}$

= $\frac{x}{24}$

So the faction of batteries which are faulty =

= $\frac{x}{24} \div x$

= $\frac{1}{24}$

Write an equation of the line in point slope form parallel to y=1/3x-5 through point (3,-7)

Mashcka [7]

Hmmm so, parallel lines have the same slope, so a line that's parallel to y=1/3x-5, will also have the same slope as that one, what would that be anyway? $\bf y=\stackrel{slope}{\cfrac{1}{3}}x-5$ , well, low and behold, since that equation is in slope-intercept form already, we can see is just 1/3.

so, what is the equation of a line whose slope is 1/3 and runs through 3, -7?

 $\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
% (a,b)
&&(~ 3 &,& -7~)
\end{array}
\\\\\\
% slope = m
slope = m\implies \cfrac{1}{3}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-7)=\cfrac{1}{3}(x-3)\implies y+7=\cfrac{1}{3}(x-3)$
